Container

Abstract

A container used in daily life comprises a container main body, and a pressure channel composed of a pressure transmission channel, a removal channel and an outflow channel connected in series. The pressure channel, attached to a wall of the container main body, has one end in communication with the removal channel and the other end connectable to a pressurizing component provided externally. The pressure transmission channel transmits pressure exerted on the inside of the pressure transmission channel by the pressurizing component provided externally, via a pressure transmission medium inside the channel. A wall of the removal channel is provided with a one-way valve allowing the contents to flow into the pressure channel. The one-way valve opens at the bottom on the inside of the container main body. The outflow channel is used for flowing out the contents from the container and preventing the contents flowing back.

What is claimed is: 
     
       1. A container, comprising a container main body, wherein the container further comprises:
 a pressure channel composed of a pressure transmission channel, a removal channel and an outflow channel connected in series; 
 a main body of the pressure transmission channel is attached to a wall of the container main body and has one end in communication with the removal channel and the other end connectable to a pressurizing component provided externally; 
 wherein the pressure transmission channel transmits pressure exerted on the inside of the pressure transmission channel by the pressurizing component provided externally, via a pressure transmission medium inside the pressure transmission channel; 
 wherein the pressure transmission channel is transparent, and an upper wall of the container main body has volume scales marked thereon; 
 wherein a wall of the removal channel is provided with a one-way valve allowing the contents in the container main body to flow into the pressure channel, and the one-way valve opens at the bottom on the inside of the container main body; and 
 wherein the outflow channel is a channel that is used for the contents to flow out of the container and able to prevent the contents from flowing back. 
 
     
     
       2. The container according to  claim 1 , wherein a horizontal position of a connection joint of the pressure transmission channel and the pressurizing component provided externally is higher than a full-load liquid level of the contents in the container main body. 
     
     
       3. The container according to  claim 1 , wherein a part of the pressure transmission channel is arc-shaped, and is located on the upper wall of the container main body. 
     
     
       4. A container, comprising a container main body, wherein the container further comprises:
 a pressurizing component; and 
 a pressure channel composed of a pressure transmission channel, a removal channel and an outflow channel connected in series; 
 wherein a main body of the pressure transmission channel is attached to a wall of the container main body and has one end in communication with the removal channel and the other end connectable to the pressurizing component; 
 wherein the pressure transmission channel transmits pressure exerted on the inside of the pressure transmission channel by the pressurizing component, via a pressure transmission medium inside the pressure transmission channel; 
 wherein the pressure transmission channel is transparent, and an upper wall of the container main body has volume scales marked thereon; 
 wherein a wall of the removal channel is provided with a one-way valve allowing contents in the container main body to flow into the pressure channel, and the one-way valve opens at the bottom on the inside of the container main body; and 
 wherein the outflow channel is a channel that is used for the contents to flow out of the container and able to prevent the contents from flowing back. 
 
     
     
       5. The container according to  claim 4 , wherein a piston is disposed in the pressure channel, one side of the piston is the pressure transmission medium, and the other side of the piston is the contents. 
     
     
       6. The container according to  claim 4 , wherein a part of the wall of the container main body is movable. 
     
     
       7. The container according to  claim 4 , wherein the pressurizing component is a structure formed by connecting a piston and a pressurizing rod, and scales are marked on said upper wall beside a pressurizing rod handle or on a support of the pressurizing rod, so as to mark the outflow volume or length of the contents when the pressurizing rod moves during pressurization. 
     
     
       8. The container according to  claim 4 , wherein the pressurizing component comprises the piston in the pressure transmission channel and a pressurizing rod, and a rod connected to the piston extends outside the pressure transmission channel. 
     
     
       9. The container according to  claim 8 , wherein scales are marked on said upper wall beside a pressurizing rod handle or on a support of the pressurizing rod, so as to mark the outflow volume or length of the contents when the pressurizing rod moves during pressurization.
